Types of Workshop Electrical Distribution Boxes

The three main types of workshop electrical distribution boxes are the Main Distribution Board (MDB), Sub Distribution Board (SDB), and Meter Panel.

1. Main Distribution Board (MDB)

The Main Distribution Board acts as the central hub for electricity in a workshop or industrial facility. It receives power from the utility supply and distributes it to various sub-circuits. The MDB typically includes circuit breakers, bus bars, and protective devices to manage load distribution and prevent overloading or short circuits. It is essential for controlling the overall power supply and ensuring safety across the entire workshop .

2. Sub Distribution Board (SDB)

A Sub Distribution Board is connected downstream from the MDB and distributes electricity to specific areas or equipment within the workshop, such as machinery, lighting, or specialized workstations. SDBs help reduce long cable runs, improve organization, and allow localized control of circuits. They often include smaller circuit breakers and protective devices tailored to the load requirements of the connected equipment .

3. Meter Panel

The Meter Panel is primarily used to measure and monitor electricity consumption in a workshop. It contains meters, primary switches, and fuses to track power usage for billing or energy management purposes. Meter panels are crucial for workshops that need to monitor energy consumption for cost control or compliance with industrial regulations .

Summary

In a workshop setting, these three types of distribution boxes work together to ensure safe, organized, and efficient power distribution: the MDB handles the main supply, the SDB manages localized circuits, and the Meter Panel monitors energy usage. Choosing the right combination depends on the workshop's size, equipment load, and safety requirements .
